What is the slope of the line on the graph

1/3

Step-by-step explanation:

Think of rise over run (y over x).

It's easiest to find exact points on the graph, like coordinate (0, -5) and (3, -4).

We can use those two points for calculations.

So between those two points, the change in y (or the "rise") is +1y.

Between these same points, the change in x (or the "run") is +3x

Since it's rise over run, the slope becomes 1/3x.

This works with any of the points because the line is linear and consistent, so the slope is the same for the whole graph.

Hope this helps!

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
